Description

Insulin injection pen

Technical field

This utility model relates to a kind of insulin injection pen, belongs to field of medical products.

Background technology

Diabetes are a kind of metabolic diseases taking hyperglycemia as feature, and the most general therapeutic modality of diabetes is insulin injection at present.Insulin uses insulin injection pen to be injected in patient's body conventionally, the insulin injection pen using is at present mainly by handwriting, a few part compositions of the pen cap and pen core frame, when use, first take off the pen cap, again pen core frame is screwed off, pen core is put into after pen core frame in cycle handwriting again, each pen core of changing is all wanted dismounting pen core frame, use very inconvenient, though current pen core must be all to adopt a property syringe needle, if in situations such as bleeding appear in injection, the head end of injection pen also easily touches virus, thereby there is viral communication.

Utility model content

For addressing the above problem, the utility model proposes one rational in infrastructure, easy to use, and can effectively prevent the insulin injection pen of viral communication.

The technical scheme that this utility model adopts is: a kind of insulin injection pen, comprise injection pen body, and be placed on the pen cap of injection pen body front end, be provided with injection push button and dosage rotary switch in the rear end of injection pen body, be provided with a pen core chamber in the inside of injection pen body front end, the sidewall of injection pen body front end is provided with the opening communicating with pen core chamber, one side of opening is hinged with vent cover, on the side of vent cover and on another side of opening, correspondence is provided with buckle and the bayonet socket for lock opening lid, sidewall at injection pen body front end is also provided with vent cover button, when use, by vent cover button, vent cover is opened, then pen core is being positioned over to pen core intracavity, lock again vent cover, be equipped with disposable lasso at the leading section of injection pen body, replaceable new disposable lasso when per injection insulin.

Further, described vent cover is provided with surplus indicating device.

Further, described vent cover is made by transparent material.

Further, described disposable lasso is rubber ring.

Compared with prior art, it has following beneficial effect to this utility model:

The handwriting of insulin injection pen of the present utility model has adopted integral type setting, while changing pen core, only need open vent cover, without dismounting back and forth, effectively simplify overall structure, use convenient, set disposable lasso can prevent that injection pen from directly contacting with patient, avoided viral communication effectively.
